Specification of Letters Patent.

Patented Oct. 24, 1905.

Application filed March 9, 1905- Serial No. 249,197.

To all It'll/072% it may cancer/1 Be it known that I, Gnonen ALvnRAno \VooDMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Brake-Heads, of which the following is a specification.

The object of this invention is to provide an adjustable brake-head capable of a multiplicity of adjustments on the brake-beam of a railway-car, the parts being constructed to interlock one with the other without employing any intermediate parts or connections.

I have illustrated one embodiment of the invention in the accompanying drawings, in which Figure 1 is a sectional view on the line 1 1 of Fig. 2. Fig. 2 is a sectional view on the line 2 2 of Fig. 1, showing the outer end of the beam broken 011. Fig. 3 is a sectional view on the line 3 3 of Fig. 1.

In the drawings, 5 is a brake-head of any suitable form provided with the cylindrical portion 6, which forms a sleeve adapted to lit upon the sleeve '7 on the brake-beam 8. The sleeve 7 may be secured on the brake-beam by a truss-rod 9, which passes diagonally through the beam and is provided with a nut at its outer end, which bears against a cap 11 integral with the sleeve 7. The sleeve thus forms a permanent and rigid part of the beam, and in the commercial practice of the art the truss-rod and the sleeve are comprehended in the term brake-beam and should be so understood in the consideration of my invention. The sleeve could be made integral with the beam; but it has been customary to make this a separate part to reduce the cost. Instead of forming the cap integral with the sleeve I may make it separate therefrom and arrange it to bear against the outer edge of the sleeve.

The head is adapted to form a locking connection with the beam, and for this purpose the head-sleeve 6 is provided interiorly with six flat faces 12, and the beam-sleeve 7 is provided exteriorly with seven flat locking-faces 13, located in adjacent relation to those on the head-sleeve and adapted to cooperate therewith. I have shown these locking-faces located at the outer end of the sleeves with the odd number on the beam-sleeve and the even number on the head-sleeve; but they may be located at either or both ends and the head-sleeve may have the odd number and the beam-sleeve the even number.

I do not limit myself to this particular number of locking-faces on the sleeves, for it is only essential that there should be an odd number on one part and an even number on the other, and the more locking-faces provided the greater will be the multiplicity of adjustments possible. To prevent the head from slipping inwardly on the beam, I provide the bolt 14, which passes transversely through the beam 8 and bears against the inner end of the sleeves.

It will be readily understood by referring to Fig. 1 of the drawings that an odd and an even number of locking-faces on the head and beam enable a multiplicity of adjustments for the head and that the number of adjustments can be increased in multiple by increasing the number of locking-faces.

The head is arranged in proper relative position and then slipped into place on the beam, and one of the locking-faces on the beam will engage a locking-face on the head that is to say, two of the locking-faces will lie parallel and in contact with each other in almost any possible adjustment. If the head is adjusted to a dilferent position on the beam, two other locking-faces will be brought into parallel relation and locking contact, and the delicacy of adjustment possible will depend upon the number of locking-faces provided.

This invention provides not only for a multiplicity of adjustments for the head on the beam, but also for securely and rigidly looking the head in place when adjusted on the beam. The sleeve 7 is prevented from moving endwise by the bolt 14 and the cap 11 and from moving rotatively by the truss-rod, nut, and cap. The cap is shown as made integral with the beam-sleeve; but this is not essential. The sleeve 6 is prevented from moving endwise by the bolt 1% and by the peripheral shoulder 15 in the offset end 6 of the sleeve, which shoulder engages the peripheral collar 16 on the sleeve 7. The engagement of the locking-faces effectually prevents any rotatable movement of the head on the beam and locks the head. securely and rigidly in its adjusted position. I have shown the sleeve 6 ofiset with the locking-faces 12 depressed therein and the locking-faces 13 formed on the peripheral collar 16 on the sleeve 7; but I do not limit myself to this particular construction.

In this invention I dispense entirely with any intermediate parts for effecting the locking engagement of the head on the beam, and this reduces the number of parts required, and thereby enhances the value and importance of the invention.

Without limiting myself to the exact construction and arrangement of parts herein shown and described, what I claim, and desire q to secure by Letters Patent, is

1. The combination of a brake-beam and a brake-head mounted thereon, one of said parts having an odd number and the other an even number of locking-faces any two of which are adapted to engage and form a locking connection between the beam and head.

2. The combination of a brake-beam and a brake-head mounted thereon, one of said parts being provided exteriorly and the other interiorly with a plurality of locking-faces, an odd number on one and an even number on the other, anytwo of said locking-faces being adapted to engage and form a locking connection between said parts.

3. The combination of a brake-beam and a brake-head each embodying a sleeve constructed to fit one within the other, one of said sleeves having an odd number and the other an.even number of locking-faces, any two of said locking-faces being adapted to engage and form a locking connection between the beam and head.

4. The combination of a brake-beam and a brake-head each embodying a sleeve constructed to fit one within the other, one of said sleeves being provided exteriorly and the other interiorly with a plurality of locking-faces, an odd number on one and an even number on the other; any two of said locking-faces being adapted to engage and form a locking connection between said beam and head.

5. The combination of a brake-beam and a brake-head each embodying a sleeve constructed to fit one within the other, one of said sleeves being provided exteriorly and the other interiorly with a plurality of locking-faces, an odd number on the beam-sleeve and an even number on the head-sleeve, said locking-faces on each part being arranged end to end and those on the head-sleeve being arranged to lie opposite those on the beam-sleeve. and any two of said locking-faces being adapted to engage and form a locking connection between the beam and head.
